    Figured I'd give local a try. Bought this. Computer wouldn't post. Tried the old PSU. No post. Sent the motherboard to ASUS. Got it back. No post. Tried my old power supply. Got it working (partially - one bad connector at the 8 year old PSU at least). Bought a PSU meter and checked this - it was giving out the wrong voltages to the motherboard. Past the return period. Probably under warranty but nothing corsair is getting another shot at my motherboard, and any PSU ever again purchased is getting tested before use on every connector.

    Was unsure about being talked into getting this item especially for my manager when we had our have a new system that has not used its warranty or a first year warranty with the manufacture so the decision was pretty much forced options due to limitations that was told

    I purchased this to replace a power supply that went bad. The computer still wouldnt power on with a new power supply. I spent some time testing/swapping the other parts and even built a whole PC because it took all of that for me to consider my new power supply could be bad. As soon as I replaced it, computer powered on. Corsair's horrible customer service gave me the run around so I returned the defective product to the store while i still could. There are indeed a bad batch of power supplies out there

    Somehow I managed to buy 2 defective power supplies in a row and now I can't return it since the proper equipment to troubleshoot took so long to arrive. 12v rails were defective and as they are built in they cannot be replaced. Only thing that worked on them were the peripherals.

    Not very impressed the power supply. Haven't had it very long then all of a sudden I lost all the PCIe connections on the power supply. Lost the GPU in any of the slots on the device. Tried another power supply and the GPU works fine.

    Crapped out in less than an hour. And this isn’t the first one of these to do that. And Corsair makes you jump through so many hoops to get it replaced. Just not worth it.

      Hi SimpleTwist,

      So sorry to hear the that PSU stopped working so soon, would you be able to try jumping the PSU to see if the issue is with the unit itself? You can try what's called a paperclip test to see if the PSU can power on itself. If you'd like assistance with performing the paperclip test, please feel free to reach out to our support team: support.corsair.com
